Figurelllis a section 0n-linel It.-lil, Fig; 9'.

Referring to the figures by characters of. reference. I designates a base of any suitable mate'- rialprovidecl at desired points with suction cups 2} formed of soft rubber or the like which are adapted to engage a flat supporting surface so asto grip the same and prevent the base. 1 from sliding after'ithas been placedin-position.. 1

v Mounted on an intermediate portion of the base is an upstanding housing 3 the bottom of which can be open,jsaid housingbeing. attached to' the. base by means of bolts. 4' or. the like. The housing? is provided with an intermediate partition 5 dividing the interior into alower'or motor chamber 6 andan upper or transmission chamber I. The

top of this housing is shaped to provide a deep cavity 8 which is extended. laterally beyond the" housing and has an outlet opening 9 extendingdownwardly through this extension. The cavity constitutes a receptacle for a dish Ill made of porcelain or other suitable'material and provided with an outlet spout ll extending into the open.- ing 9. This dish is removably seated in the cav ity so that it can be cleaned readily; A removable cover l2 engages the top of the. housing and,

when in position, completely closes the top'of' the cavity and the dish therein. I

A bearing sleeve I 3; is integral with and extends downwardly from the top of the housing 3 and is providedwith' a shaft-receiving opening M which substantially registers with or is coaxial with an opening [5 provided in the bottom of the dish l0", this dish being preferably thickened at the opening l5 to provide requisite strength. This thickened portion is in the. form of a sleeve l6 integral with the dish.

Secured Within the housing 3 where it is fixedly positioned within the chamber 6, is an electric motor l? having a shaft l8i extending. upwardly therefrom through, a bearing l9 in partition 5 and thence through the opening M and upwardly above the top wall of the housing. The upper part of this shaft, which is exposed within the cavity 8 is adapted to be removably engaged by a sleeve 20 secured within and'extending downwardly from a, reamingv head or extractor 2i. shaped to extend loosely around the sleeve. l6 and being substantially semi-ovoid with surface ribs or grooves suchv as commonly employed in juice extractors. Sleeve 20 can be provided with an angular recess therein andthe shaft it can have. its. upper end similarly shaped. so that. when the sleeve is in position, it will be driven by the-shaft. This is such an obvious construe.- tion that it is not deemednecessary to illustrate it in detail.

A gear 222 is secured. to the shaft 18 within chamber 1 and is in. constant mesh with a gear 23 secured to an intermediate shaft 24 journaled in the top wallof the housing and also-in a bearing 25 in partition. 5. Thisshaft has aworm 25 in constant mesh. with a worm .gear 2'! secured to a laterally extended shaft 28, journaledi at one end to the sleeve l3, as shown at 2'9, whileits other endis-journa'led in a bearing an in one wall of. the housing. 3 and is extended laterally therebeyond where it has an angular terminal 3 l.

The basal provides. a seat 32 beneath the opening 9 forrecei'ving a removable container33.

the container will be supported close to one side of the housing 3 and directly under the,

outlet opening 9 so that juices extracted within the dish 10 can gravitate downwardly through the spout I I and into the dish 33.

At the other side of the housing 3 the base i is provided with a seat 34 for an elongated dish 35.

That side of the housing 3 nearest the dish 35 is provided, close to its upper end, with screwthreaded recesses 36. These are adapted to receive bolts 31 for detachably securing to the housing 3, certain supplemental elements to be used in connection therewith. One of these elements, designed for extracting juices from vegetables, meat, or the like, includes a casing 38 having a longitudinal recess 39 in the bottom portion thereof which is tapered toward one end, the bottom of the recess or chamber 39 being formed with longitudinal slots 40 which diverge downwardly as indicated in Fig. 6. That end of the recess or chamber 39 nearest the housing 3 is larger than the other end and has opening into the top thereof a feed opening 4| which is preferably flared upwardly away from the chamber.

A tapered worm 42 is mounted concentrically within the chamber 39 and has a recessed stud 43 extended from the center of the large end thereof, the recess in said stud being proportioned to fit snugly upon the angular end of shaft 23 so that when the parts are assembled, motion will be transmitted from said shaft to the worm. Another stud 44 is extended from the other or small end of the worm and is journalled within a cross-bar 45 which bridges the small end of the chamber 39 and is held detachably in place by means of bolts 46. Thus spaces are left at opposite sides of this bar through which waste matter can be extruded. When the casing 38 is secured in position it will be supported directly over the dish 35.

Instead of using the supplemental structure shown in Figs. 2 to 6, a grinding element can be attached to the housing 3 as shown in Figs. '7 to 10 inclusive. This includes a casing 47 having a longitudinal chamber 48 provided at one end with a feed opening 49. A substantially cylindrical feed worm 59 is supported within the chamber 43 by means of a recessed stud 51 at one end for engagement with the angular end of shaft 28 and another stud 52 at its other end. This latter stud is journaled within lapping disks 53 and 54, clamped within the end of the casing 41 by a threaded ring 55. Knives 55 are rotatable with the stud 52 and are adapted to wipe across the inner ends of openings formed in the inner disk 54.

This casing 4'! is adapted to be secured to the housing 3 in the same manner as the casing 33 previously described, the bolts 31 being used for that purpose. The two disks 53 and 54 can be rotated relative to each other so as to move their openings relative to each other, thereby to contract the spaces or outlets provided by the openings, if desired. After adjustment the disks are clamped securely in place by the ring 55'.

In practice the motor I! can be started by shifting a suitably located switch, not shown, whereupon the head 2! will be directly driven by the shaft I8 so as to rotate at a high speed. By removing the cover l2 the portion of a fruit from which juice is to be extracted, is pressed downwardly onto the rapidly rotating head in the usual way so that the juice thus extracted can flow outwardly through the spout H and into the dish 33. During this operation, shaft 28 is bei g driven at a slow speed by the speed reduction gearing consisting of gear 21, worm 26, and gears 23 and 22. If the casing 38 is in position and it is desired to extract juice from meat or vegetables, the worm 42 will rotate at a slow speed and the material to be acted on is forced downwardly through the opening 4| so that it will be engaged by the worm and thrust longitudinally toward the small end thereof. This will result in extreme compression of the material so that juices therein will be extracted and can flow downwardly through the slots 40 in the bottom of the chamber 39 where the dish 35 can retain them. When the chamber 39 becomes packed with fibrous matter, the bar 45 can be removed and the material withdrawn from the small end of the chamber 39. At other times, while this bar is in place, the spaces left at the sides of the bar, permit the escape of air in advance of the material to be ground is supplied to the worm 50 through the feed opening 49. The disks 53 and 54 are adjusted by rotating them relative to each other so as to provide full size openings as shown in Figure 7, or openings of reduced size as shown in Figures 9 and 10, and material will be fed longitudinally between the cutting knives 56 and forced through the openings in the disks 53 and 54. The knives will cut off the material so that it will be extruded in fine particles through the openings.

A deflecting hood 58 opening downwardly over the container 35, can be removably mounted on the casing 4! over and beyond the ring 55.

What is claimed is:

Food treating apparatus including a motor and transmission housing including a base having a receptacle supporting seat extending laterally therebeyond, a shaft extending laterally from the upper portion of the housing, a casing having a material inlet in the top thereof and downwardly diverging longitudinal slots in its bottom, said slotted portions overlying the seat at the bottom of the housing, there being an aperture in one end of the casing into which the shaft projects, thereby providing a bearing for the shaft, means for securing the casing detachably to the housing, a bar bridging the other end of the casing and detachably secured thereto, and a tapered worm mounted for rotation in the casing and operatively connected at one end to the shaft, said worm being detachable with the casing from the housing and the shaft.
